ICD-10 Code H33.043 – Retinal detachment with retinal dialysis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.043 – Retinal detachment with retinal dialysis, bilateral
What it is
This code identifies a retinal detachment in both eyes caused by retinal dialysis, a separation of the retina at its peripheral attachment. Use it when documentation clearly states bilateral involvement.
Clinical signs
Findings may include decreased vision, flashes, floaters, or a peripheral visual field defect. Diagnosis is usually confirmed by eye examination and retinal imaging; clinical features vary, so refer to documentation.
When to use this code
Use H33.043 when the provider documents bilateral retinal detachment specifically associated with retinal dialysis. It applies when both eyes are affected and the record does not indicate a different retinal detachment subtype. If laterality is unclear, check documentation before coding.
Do not use for
Do not use this code for unilateral retinal detachment, retinal tears without detachment, or detachments from other causes. If the note does not specify retinal dialysis or bilateral involvement, check documentation.
Coding tip
Verify both laterality and the exact detachment cause in the ophthalmology note before assigning H33.043.
